Abstract: Noble Energy recently began oil exploration activities in northeastern Nevada to determine the potential for unconventional oil plays. The oil play is in a low permeable shale and will require hydraulic fracturing. The Nevada Legislature passed a bill in 2013 requiring adoption of new regulations guiding hydraulic fracturing and also paved the way for a study to determine the migration potential to shallow groundwater resources. The Desert Research Institute (DRI) just completed the Aquifer Quality Assessment Program (AQUA) study which collected baseline and post-fracking groundwater quality data and developed numerical modeling tools to assess the migration potential of hydraulic fracturing fluids to the shallow aquifer. This presentation will discuss results from the AQUA study which indicate that water quality has not been degraded following hydraulic fracturing. The numerical modeling suggests that hydraulic fracturing fluids are not likely to migrate to the shallow aquifer at concentrations greater than detection within the next 1,000 years.

Biography: Dr. Pohll is a research professor of hydrogeology at the Desert Research Institute in Reno, NV. He is an expert in the field of hydrogeology with over 20 years’ experience solving real-world problems within complex hydrologic systems that require tools from the fields of surface water hydrology, groundwater hydrology, and statistics. Dr. Pohll’s primary research focus is related to the development of three-dimensional groundwater flow and transport models for local and basin-scale assessment of water resources and groundwater contamination issues. In addition to his research responsibilities, he also teaches and advises graduate students within the Graduate Program of Hydrologic Sciences at the University of Nevada, Reno.

The McDermitt caldera of northern Nevada and southeastern Oregon is a large, 16.4 Ma volcanic center that is commonly recognized as the starting point of the Yellowstone hotspot, which migrated northeastward over time to the Yellowstone National Park area where volcanism continues to be intensely active (Pierce and Morgan, 1992, 2009). New geologic mapping and analytical studies by geologists with and working with the Nevada Bureau of Mines and Geology reveal the overall characteristics, dimensions, timing, and relation to mineralization of the caldera. The caldera formed when about 1000 km3 (about 250 mi3) of mostly rhyolite magma erupted from an underlying chamber. So much magma erupted that the overlying ground collapsed into the resulting void, leaving a giant depression—a caldera—that was about 40 km north-south by 22 to 30 km east-west. The giant eruption was preceded by additional volcanism that began about 16.85 Ma and was followed by volcanism that lasted episodically until about 14.9 Ma. Hydrothermal activity related to the volcanism generated numerous known and probable mineral deposits in and around the caldera, especially of the strategically important minerals lithium, uranium, and gallium. Additional, currently unknown areas and types of mineral deposits are likely.
